I am quite aware of what that particular setting does, but if you read
towards the bottom of the description you find this:
Also, see the "Remove search box from Start Menu" and "Remove Search button
from Windows Explorer" settings.
It references another setting called "Remove search box from Start Menu".
When you try to find this setting you find that it does not exist.
Here is the whole description:
Removes the Search link from the Start menu, and disables some Windows
Explorer search elements. Note that this does not remove the search box from
the new style Start menu.
This setting removes the Search item from the Start menu and from the
context menu that appears when you right-click the Start menu. Also, the
system does not respond when users press the Application key (the key with
the Windows logo)+ F.
In Windows Explorer, the Search item still appears on the Standard buttons
toolbar, but the system does not respond when the user presses Ctrl+F. Also,
Search does not appear in the context menu when you right-click an icon
representing a drive or a folder.
This setting affects the specified user interface elements only. It does not
affect Internet Explorer and does not prevent the user from using other
methods to search.
Also, see the "Remove search box from Start Menu" and "Remove Search button
from Windows Explorer" settings.
Note:
This setting also prevents the user from using the F3 key.
